ELITE SLWR: global 1km daily SLDR at SIN Grid (2011_182-243)

The Essential thermal Infrared remoTe sEnsing (ELITE) product suite currently has four types of products, including land surface temperature (LST: clear-sky and all-sky), emissivity (NBE: narrowband emissivity; BBE: broadband emissivity; and spectral emissivity), the component of surface radiation and energy budget (SLUR: surface longwave upwelling radiation; SLDR: surface longwave downward radiation SLDR; SLNR: surface longwave net radiation), and the component of Earth’s radiation budget (OLR; outgoing longwave radiation; RSR: reflected solar radiation). The spatial-temporal resolutions of the ELITE products are mainly determined by the employed satellite data sources. For more information about ELITE products, please refer to the website (https://elite.bnu.edu.cn).

This dataset is ELITE daily surface longwave downward radiation (SLDR) product at 1km spatial resolution. It is provided on a Sinusoidal grid and ranges from 2000 to 2022 (continuously updated). This dataset was generated from the ELITE surface longwave downward radiation (SLDR) product using the algorithms developed by Zeng et al. (2021).

This is the ELITE Daily SLDR product in 2011 (DOY: 182-243). Please click here to download the ELITE Daily SLDR product in 2011 (DOY: 244-304).

核心热红外遥感（Essential Thermal Infrared Remote Sensing，ELITE）产品套件目前包含四类产品，分别为：地表温度（Land Surface Temperature，LST：晴空与全天空两种产品）、发射率（含窄带发射率Narrowband Emissivity，NBE；宽带发射率Broadband Emissivity，BBE；以及光谱发射率）、地表辐射与能量收支组分（含地表长波上行辐射Surface Longwave Upwelling Radiation，SLUR；地表长波下行辐射Surface Longwave Downward Radiation，SLDR；地表长波净辐射Surface Longwave Net Radiation，SLNR），以及地球辐射收支组分（含出射长波辐射Outgoing Longwave Radiation，OLR；反射太阳辐射Reflected Solar Radiation，RSR）。ELITE产品的时空分辨率主要由所用卫星数据源决定。如需了解ELITE产品的更多信息，请访问官网：https://elite.bnu.edu.cn。

本数据集为空间分辨率1km的ELITE每日地表长波下行辐射（SLDR）产品。该数据采用正弦网格（Sinusoidal Grid）进行组织，时间跨度为2000年至2022年（持续更新中）。本数据集基于Zeng等人（2021年）提出的算法，由ELITE地表长波下行辐射产品生成。
